Systematic variation of the stellar initial mass function in early-type galaxies
(2012-04-26)
Much of our knowledge of galaxies comes from analysing the radiation-emitted by their stars, which depends on the present number of each type of star in the galaxy. The present number depends on the stellar initial mass ...
The ATLAS(3D) project - VII. A new look at the morphology of nearby galaxies: the kinematic morphology-density relation
(2011-09)
In Paper I of this series we introduced a volume-limited parent sample of 871 galaxies from which we extracted the ATLAS(3D) sample of 260 early-type galaxies (ETGs). In Papers II and III we classified the ETGs using their ...
The ATLAS(3D) project - I. : A volume-limited sample of 260 nearby early-type galaxies: science goals and selection criteria
(2011-05)
The ATLAS3D project is a multiwavelength survey combined with a theoretical modelling effort. The observations span from the radio to the millimetre and optical, and provide multicolour imaging, two-dimensional kinematics ...
